What is specific gravity of caustic soda?
It depends on the solution's degree of concentration or dilution.
When more solvent is added to a solution to decrease its concentration it is called?
When more solvent is added to a solution to decrease it's concentration the action is known as dilution.
What happens to the concentration of hydroxide ions in an alkaline solution on repeated dilution?
The number decreses and the pH lowers
What is sequential dilution?
In a sequential solution different volumes of a stock solution is added to varying volumes of solvent to create new solutions of specific concentration. Mostly use to create lower concentration of solutions.
What is the term used to describe a solution that has a lower concentration of solutes compared to another solution?
Lower concentration of solute is known as the hypotonic solution. The solution with a higher concentration of solute is the hypertonic solution. One with equal solute in solution and whatever its being compared with is known as the isotonic solution.
How does dilution affect concentration of a solution?
Dilution reduces the concentration of a solution.
What is infinite dilute solution?
Infinite dilution means such a large dilution so that when you add more solvent there is no change in concentration.

When more solvent is added to a solution to decrease its concentration it is called?
When more solvent is added to a solution to decrease it's concentration the action is known as dilution.
What is the total dilution factor from 1.00 M NaCl to 1.00 M NaCl solution?
The concentration is the same !
What happens to the concentration of hydroxide ions in an alkaline solution on repeated dilution?
The number decreses and the pH lowers
What happens to the concentration of hydrogen ions in a 1 moles per liter solution of hydrochloric acid on repeated dilution?
The concentration become more and more lower.
What is sequential dilution?
In a sequential solution different volumes of a stock solution is added to varying volumes of solvent to create new solutions of specific concentration. Mostly use to create lower concentration of solutions.
What does dilution and concentration mean?
Dilute it when there isn't much solute in the solution. So there is a lot of solvent. Concentrated mean there is a lot of solute in the solution.
What is the term used to describe a solution that has a lower concentration of solutes compared to another solution?
Lower concentration of solute is known as the hypotonic solution. The solution with a higher concentration of solute is the hypertonic solution. One with equal solute in solution and whatever its being compared with is known as the isotonic solution.
How do you solve a dilution problem in Chem?
The key formula for solving a dilution problem is M1V1=M2V2 (alternately, MAVA=MBVB) where concentration is M (measured in Molars, a unite of concentration-->Molars=moles solute/Liters solution) and the volume of solution is V. M1V1 represents the inital conditions (pre-dilution), and M2V2 denotes the final conditions (post-dilution). Plug in the three values you know to find the fourth value, which you are solving for. Ex. 750mLs of a 0.5 M NaC2H3O2 solution is diluted with 250mL of H2O. What is the new concentration of NaC2H3O2? Answer: (0.5M)x(.750L)=(MB)x(.750L+.250L) 0.375ML=(MB)x(1L) MB=0.375M
Definition of dilution and dilution factor?
In chemistry and biology, the dilution factor is the total number of unit volumes in which the material is dissolved. As I understand it, the dilution refers to the dilution ratio. If you add 1 part of something to 4 parts of something else, the dilution ratio is 1 to 4. The dilution factor counts all the parts and expresses the same thing as 1 out of 5.
